SILO-TILE.

Specification of Letters Patent.

Patented Dec.. 28, 1915.V

To all whom z5 may concern.'

Be it known that we, JOSEPH AV. AYER and `WILLIAM L. MCCAREL, citizensof the United States, residing at Brazil, Clay county, and State ofIndiana, have invented and discovered certain new and usefulimprovements in Silo-Tiles, of which the followingy such intervals andlocations, and of suchv form as to obtain an effective mortar jointbetween adjacent tiles.

TVith the above object in view our invention is embodied in preferableform in the tile hereinafter described and illustrated in theaccompanying drawing.

In the drawing the view shown is a perspective end view of the tile.

Referring to the drawing, the tile is preferably constructed of clay andhas two large openings 1 and 2 extending longitudinally of the tile asis usual in such construction. rFliese openings leave an upperhorizontal cross wall 3, a lower horizontal wall f1, a central cross web5 and two vertical side walls 6 and 7. The upper opening has an `innerupper flat face 8 parallel with the upper outer face 9 of the tile, andvertical side faces 10 parallel with the outer vertical plane face ofthe side wall of the tile. The horizontal inner faces of the top andbottom walls and the side faces 10 are joined by inclined or angularcorner faces 12, leaving a comparatively wide space between each face 12and the opposing portion of the outer face of the side wall of the tile.The inner corners of the opening l are joined by shorter angular faces13. The lower opening 2 is formed similarly to the upper opening 1 withwide angled outer corners and shorter angled inner corners.

1n each side wall of the tile is formed a series of longitudinallyextending apertures providing dead air spaces preferably live in number.rl`he upper and lower spaces 14 of each of these series are constructedalike and each has a vertical face 15 parallel with the vertical sidesurface of the tile, a horizontal outer face 16 yparallelwith the`horizontal faces of the tile and an angular face 17 which-isparallelwith the inclined face 12 of the adjoining large opening 1 or 2,1 andwhich inclined face is spaced from said face 12. The outer face of thetriangular air spaces 11 thus formed, is preferably on a line with thehorizontal faces 8 of the central openings and the inner terminations ofsaid openings 14 are preferably on a line with the inner corners. of theinclined faces 12.

Between the spaces 14 inthe side webs of the tile are formedlongitudinal apertures forming air spaces 18 substantially opposite thecentral portion of the largeopenings 1 and y2 respectively. These spaceshave outer' vertical side faces 19 and inner side faces 20 which arelonger than the outer faces 19, and said side faces arejoined by angularend faces 21 whichl are in continuation of the lines of the corners 12and 13 of the large central openings.

Between the spaces 18 in eachv side wall of the tile and opposite thecentral crossweb 5 is formeda longitudinal air space 22 of triangular'form and having a vertical side face'23and two inclined faces 241, whichex tend inwardly and which are parallel to the linesof the corners 13Aof the central openings and the end faces 21 of the openings 18.

By'the above construction and arrangement of the central openings andlateral air spaces, angularly formed web portions will be provided inthe side walls of the tile as indicated by the numerals 25, 26, 27 and28. Such angular formation of the side walls leaves wide areas betweenadjacent openings and strengthens the tile and resists lateral pressurefrom the adjoining tiles which is a feature of great importance in siloconstruction. The angular ends of the spaces 18 and the angular corners13 of the central openings in conjunction with the inner inclined faces211 of the openings 22, enable these latter openings to be placedopposite the central cross web without impairing the strength of thewalls of the tile at this point and thus permit a sufficient number ofopenings to be formed in the vertical side walls to obtain a mortarjoint of effective length.

Mortar is adapted to. be placed along the end edges of the air spaces inthe side walls and when two tiles are placed together end to end, themortar will be forced slightly within these openings, thus locking thetiles firmly together. The outer line of the walls of these air spacesforms a straight vertical line but the inner edges owing to the inclinedwalls 17 and 24 of the triangular air spaces form a broken line, and theinclinations of said walls being between a vertical and a horizontalline, tend to resist both vertical and lateral stress, and thus aid inmore effectually maintaining the mortar joint intact.

Having thus described our invention what we claim is:

l. A tile having side walls provided with continuous vertical planeouter faces and parallel inner faces and having top and bottom wallswith horizontal parallel inner and outer faces, said tile having angledlinner corner surfaces joining said inner vertical.

and horizontal faces, said walls having longitudinal apertures in thecorners thereof, the surfaces of which are parallel respectively to theinner vertical, horizontal and corner faces of the tile.

2. A tile having a large longitudinal opening and having top and bottomhorizontal walls and vertical side walls, said walls having in thecorners thereof longitudinal apertures with vertical and horizontalfaces and with an inclined face joining the vertical and horizontalfaces and said vertical side walls having a plurality of longitudinalapertures therein between said corner apertures, said intermediateapertures having the faces thereof which extend from the outsideinwardly inclined to the horizontal, the adjacent faces of adjoiningopenings being parallel, whereby angularlyr extending web portions inthe side walls are provided.

Copies of this patent may be obtained for 3. A hollow tile having largecentral longitudinal openings therein, a central cross web spacing saidopenings apart, said tile having angular faces at the inner corners ofeach of said openings, the side walls of the tile having longitudinalair space apertures opposite said central web, each of said openingshaving a vertical outer face and inclined inwardly extending facesrespectively parallel to the angular corner faces of the upper and lowerlarge central openings.

4f. A hollow tile having large central longitudinal openings spacedapart vertically lea ving a central cross web and having angular innerand outer faces at the corners of said openings, the outer corner facesbeing longer than the inner faces, said tile having a series of angledair spaces in each side wall of the tile comprising upper and lowerspaces each having a face parallel to the outer angular corner face ofthe adjacent large openings, which side wall having an air spaceopposite the central cross web which has in wardly extending facesrespectively parallel to the inner corner faces of the upper and lowercentral openings, and air spaces between the end spaces and said middlespace having inwardly extending angular faces respectively parallel tothe adjacent faces of the spaces above and below it.

In witness whereof, we have hereunto set our hands and seals at Brazil,Clay county, Indiana, this 10th day of April, A. D. nineteen hundred andfifteen.
